The Netherlands is not exactly what you'd call a mountain biking mecca. While it has the whole 'biking' thing down better than probably any other country on the planet, the fact that a lot of the country is actually below sea level means it's somewhat lacking in the 'mountain' department. Despite this, it definitely punches above its weight in the MTB world with Mathieu Van Der Poel one of the favourites for Olympic gold next year and a lineage of great riders including Bas de Bever, Bart Brentjens and Anneke Beerten.
Hoping to be another mtb name to remember from the Netherlands comes Instinctiv Bikes.

instinctiv.bike The brand's first platform is the M Series that is available with 29", 27.5" or mixed wheels. The bikes all use the same front triangle, but the seatstay and chainstay are different for the bigger rear wheel on the M9 29er. The frames have been two and a half years in the making and are the brainchild of CEO Andreas Knol. The bikes started as a side project of Alskar Design, a design and engineering company that Andreas also founded, but has now grown into its own company.
Andreas said: "About 2.5 years ago I got the desire to create our own product, to showcase what we are capable of doing as a team. To develop our own high-end bike, bringing every detail to a high degree of perfection. That was the start of Instinctiv. It started as a project but evolved into a company that designs, develops and assembles bikes."
Frame DetailsInstinctiv's frames are full carbon and it claims the weave it uses comes from a "premium automotive brand". The frames also use 7% recycled carbon fiber, which Instincitv knows isn't going to change the world but it said, "we don’t want to wait until everything is right. We wanted to make a small start now and believe that it is possible to push limits further in the future." The frames are made in Taiwan but painted and assembled in the Netherlands.
The large front triangle is probably the most noticeable aspect of this bike. Combined with the low slung shock, this gives room for two water bottles. Only shortly after noticing the front triangle, you'll probably see that this is a gearbox driven bike too. The bike uses Pinion drivetrains but Instinctiv has made some modifications including a chain tensioner that Instinctiv claim reacts faster than the standard one. Instinctiv's jockey wheel uses a different spring system, larger jockey wheels, high quality bearings, and a closed construction to bring about some improvements on the original design.
Instinctiv also attempted to fix a big problem on the Pinion and have replaced its GripShift with a proprietary shifter. The shifting module is from Cinq / Tout Terrain, a German manufacturer, in combination with Instinctiv's own ergonomic trigger that it claims gives a shifting feeling similar to a derailleur set up we are all used to.
Instinciv's modifications are designed to improve the performance of the Pinion gearbox.
GeometryInstinctiv describes the bike as suitable for enduro and trail riders and believes it "could perform well in the EWS'. The M9 and the M7 share very similar geometry numbers but the M97 is a bit slacker thanks to the mismatched wheels. The head angle on the M9 and M7 sits at 64.5° but half a degree slacker on the M97. The same is true on the seat angle where 76° slackens out to 75.5° on the mixed version. The bikes have a healthy reach across sizes with 486mm in size large, again this is a bit different on the mixed wheel version by around 5mm per size.
The other big discrepancies between the bikes come from the chainstays where the M7 and M97 have compact 430mm stays but these stretch out a bit on the M9 version to accommodate the bigger wheels.
SuspensionInstinctiv designed its suspension to be as central, low and compact as possible to complement the weight distribution offered by the gearbox. Instincitv claims that this layout gives the bike, "stability at high speed, a lot of grip and a predictable character in all conditions"
It's essentially a Horst Link but with a system of rockers and links that drives the shock in a very progressive and compact way. This 'Puma' platform is patented and allows Instinctiv to "optimise the leverage ratio independent of other kinematic factors."

The brand is currently prioritizing slow and steady growth so it can logistics, quality and manufacturing at a high level. It is currently exploring some other models and we will update you when we hear more. For more information on Instincitv bikes, click

My zerode has the stock pinion chain tensioner so I don't drop the chain midway through travel. I never notice it's there when on the bike, which is nice.
There is also the Rohloff Gates Full Suspension SVC Strato Bike 2 - belt drive and no tensioner.

Big enough to protect the old 3X's we started out with. Should do the job.

If you can pivot the rear suspension off the gearbox drive shaft in a single pivot design there will be no change in chain length and a tensioner will not be necessary. Using a multi link design or a single file pivot with a main pivot not exactly on the drive shaft will result in changes in chain tension.
I think there was a French bike with the Effigear gearbox on PB last year that had a high pivot on the gearbox output shaft. It had a name in some way related to Star Wars I seem to recall.
The reason high pivot bikes have the idler is not because there is no chain growth. Quite the opposite. There is so much chain growth that without the idler the chain would grow too much and probably snap at the bottom, or be too slack at the top, or both.
I thought so too but talking about it on a messageboard I had the opposite opinion, and this may make sense because as you say the rear moves much more, so if the BB mounted tensionner is not powerfull enough, you may still have enough slack in the chain which may then get off the rear cog.
Inversely, as the BB doesn't move much, you don't need the tensioner in the area, and you'd better place it in the rear.
To sum up : If the tensioner fails to properly tension the chain, it will act as a chain guide and will then be more helpfull at the rear which moves a lot than around the BB which moves much less.
At least that's what I understood.
The wheel with the tensioner in that position becomes a bash guard of sorts. I doubt you would hit it much there anyways.
There are some pretty compact single speed tensioners out there that are high up, tucked in and like a normal rear derailleur they are way behind the rear wheel.

To play devils advocate I'd hope they spent enough time testing their design that it's not an issue... Might just look off and be a non issue? (hope that's true of the humpback tall top tube too!)
Just seems like there could have been a better solution...
I have smacked 7 rear derailleur instead for the last 3 years.
This is out in front of the rear wheel and below the chainring, a normal derailleur is way in the back of the bike with only side/glancing blows to worry about.
I don't get the argument here. Go look at how Zerode did it and tell me that isn't a better set up?
For a trail bike, I think its kinda not really worth it, but for enduro/dh (like with Nicolai) gearbox with belt drive is almost the suprerior alternative. For the ups, you really just need the bike to have decent range and non crap kinematics without focus on efficiency. For the downs, the lack of weight on the rear wheel, no chain loss, much better environment resistance, and instananeous shifting without pedaling are all advantages that are worth the loss of efficency.

That’s massive room of adjustment
Guess it will make for awesome frame bag space...?
If you rode this bike with that seat height because you needed this much reach it would just be a matter of time till CRUSHED...

I said the stand over numbers were OK. But you have to consider how quickly that stand over is infringed due to the angle of the top tube so in real life, say an OTB situation where your violently flung forward you have less clearance than ideal IMO.
There are only three sizes, some people will likely size up to the medium and have a huge bassed TT between their legs...
I haven't bought a bike in years now that didn't keep most of its tubes and suspension under an almost straight line from the top of the headtube to the rear axle. I still own a few bikes that use a bunch of real-estate above that line. However, I notice it getting in the way. Especially on slow technical stuff, up or down. And skinnies... i doubt these bike designers ever failed a skinny ended up landing on the top tube.
I think Kona really started pushing that "keep it low" thing with the Process 111 a few years back, but there were probably others...
...or maybe european super-cyclists just don't fail skinnies or slow technical stuff ... that could be it... youtu.be/GDwVXxYbLeM
...or maybe I just crash too much?...
I mean bikes coming out like the transition spur / scout and yt izzo look so sharp - straight lines is where it’s at in 2020. This has got more curves than a milf porn site.
I can confirm, this was one of the biggest perks of riding a Pinion bike, and it really surprised me how noticeable it was
..Now what do we do with this thing?
Engineer - I KNOW!!!
Could have been quite attractive, Could have been elegant, but ended up being forced and extraneous.
Front triangle COULD have looked like a Scott Ransom, + the little top tube/downtube connector.
But then it would have been closer to a Mondraker, and then the comments would have been aflame for other reasons.
And what's with the suspension video?!
Did they actually leave the shock at full pressure, then attempt to show us something, but ended up showing us 30% shock and 70% tire squish?
A small company might get one shot at an audience like this. Not a good time to flail.
It's called slow painful death in public

So if a company is going to use a gearbox that necessitates a tensioner, why not step up and make it a high pivot?
I want a high pivot gearbox!
